TS 12664-2/T3

TS 12664-2/T3 addresses general rules for workplaces that carry out the conversion of road vehicle propulsion and fuel systems for use with compressed natural gas (CNG) and liquefied natural gas (LNG). Its focus is the workplace framework that supports these conversion activities through structural, operational, personnel-related and technical equipment provisions.

In this type of facility, the subject is not only installation work but also the way the job is organized around the physical characteristics of gaseous fuels. CNG is stored at high pressure, while LNG is kept in liquid form at very low temperatures. For that reason, layout, ventilation, equipment arrangement, staff competence and operating discipline become especially important in relation to the fuel type involved.

What matters in a CNG/LNG conversion workplace?

• Structural arrangement: separating work areas, storage areas and processing zones according to function
• Operations: controlled workflow, records and responsibility arrangements
• Personnel: a level of knowledge and preparation suitable for the tasks performed
• Technical equipment: tools and auxiliary equipment compatible with CNG and LNG work
• Workplace context: an orderly, inspectable setting suitable for gas-system related activities

From a general technical perspective, the standard defines a baseline workplace framework for facilities that convert vehicles to gas fuel systems. That helps similar conversion activities be carried out with a comparable level of organization and technical discipline across different workplaces; however, this record should not be read as a product approval or as a full step-by-step installation manual.

In short, TS 12664-2/T3 is a technical reference for aligning the physical infrastructure and operational organization of workplaces involved in CNG and LNG vehicle conversions.
